Product Overview
TPS65023 is a Texas Instruments Power_Management PMIC integrating three step-down converters, two 200 mA general-purpose LDO regulators, and a 30 mA VRTC LDO and switch for real-time-clock support. The converter set is identified for processor core, system voltage, and memory voltage rails, with DCDC1 rated at 1.7 A, DCDC2 rated at 1.2 A, and DCDC3 rated at 1.0 A.
The device supports serial control through an I2C interface compatible with standard and fast mode operation up to 400 kHz. For the TPS65023 variant, the I2C setup and hold timing is 300 ns; for TPS65023B, it is 100 ns. Dynamic voltage management is supported for the processor core converter through the serial interface.
TPS65023 is offered in a 40-pin WQFN package with a 5.00 mm x 5.00 mm nominal body. It operates across a -40°C to 85°C free-air temperature range and has 85 uA quiescent current. Additional functions include four default LDO voltage combinations selected by DEFLDO1 and DEFLDO2 pins, externally adjustable reset delay, battery backup, separate converter enable pins, low-ripple PFM mode, and thermal shutdown protection.
